SOME OBSERVATIONS ON METRIOPTERA ROESELII (GRYLLOPTERA: TETTIGONIIDAE) IN MAINE, NEW HAMPSHIRE, AND MASSACHUSETTS

Metrioptera ( Roeseliana ) roeselii (Hgb.) was first introduced into the Montreal, Que., area before 1952. By 1965 it had been collected in western and southern New York State. This paper records it from Maine, Massachusetts, and New Hampshire for the first time, and discusses the populations. Eventual establishment of M . roeselii over all of New England is predicted.
